In the modern world, robotics has become popular, useful and has achieved great successes in several fields of humanity. Every industrialist cannot afford to transform his unit from manual to semi-automatic or fully automatic as automation is not that cheap in India. The basic objective of this project is to develop a versatile and low cost robotic arm which can be utilized for Pick and Place operation. Here controlling of the robot has been done by using servo drives and arduino microcontroller. This robot is having 4 DOF and controlled by android app with Bluetooth interfacing. This Robotic arm can be used in number of applications by changing the program of controller and end effector, so that it would be used mainly in the automatic assembly lines. Key Words: SCARA, Degree of Freedom (DOF), Arduino, Bluetooth Interfacing, Design, Manufacturing, Analysis. 1.INTRODUCTION The purpose of using robotic arm is to reduce errors and human efforts. As the robotic field is having an application in various department of engineering such as production, inspection, material handling etc. This type of robotic arm is famous for its characteristics like high speed, good accuracy, less maintenance and repeatability in pick and place operation which is required in assembly. This case study is concern with design, manufacturing and analysis of mechanical structure of SCARA. The SCARA stands for Selective Compliance Assembly Robot Arm having 4 degrees of freedom in which one is linear motion and three rotational motions. This robotic arm is electrically actuated by using DC servo motors for achiving three rotational motions and one DC geared motors for linear vertical motion. These motors are controlled by C-programming language in Arduino Genuino 1.8.5 software as required for pick and place operation of object having dimensions 20x20x50mm. To command the robotic arm by using mobile android app, Bluetooth module HC05 is used which make it user friendly and ease of giving task. 2. LITERATURE REVIEW 1. Design and Fabrication of Pick and Place Robot to be used in Library by Anusha Ronanki, M. Kranthi: The use of robots in library is becoming more popular in recent years. The trend seems to continue as long as the robotics technology meets diverse and challenging needs in educational purpose. The prototype consists of robotic arm along with grippers capable of moving in the three axes and an ATMEGA 8 microcontroller. Software such as AVR Studio is used for programming, PROTESUS is used for simulation and PROGISP is used for dumping the program. RFID is used for identifying the books and it has two IR Sensors for detecting the path. This robot is about 4 kg in weight and it is capable of picking and placing a book of weight one kg.s. 2. ROBOT ARM CONTROL WITH ARDUINO By Abdellatif Baba Today, technology is developing in the same direction in line with rapidly increasing human needs. The work done to meet these needs makes life easier every day, and these studies are concentrated in robotic arm studies. Robot arms work with an outside user or by performing predetermined commands. Nowadays, the most developed field of robot arms in every field is the industry and medicine sector. Designed and realized in the project, the robot arm has the ability to move in 4 axis directions with 5 servo motors. Thanks to the holder, you can take the desired material from one place and carry it to another place, and also mix it with the material it receives. While doing this, robot control is provided by connecting to the android application via Bluetooth module connected to Arduino Nano microcontroller. 3. Pick and Place Robotic Arm Implementation Using Arduino Ashly Baby1 , Chinnu Augustine2, Chinnu Thampi3, Maria George4 , Abhilash A P5 ,Philip C Jose6 A robotic arm is designed using arduino to pick and place the objects via user commands. It will pick and place an object from source to destination safely. The soft catching gripper used in the arm will not apply any extra pressure on the objects. The robot is controlled using android based smart phones through Bluetooth. Based on the commands given by the user the robot moves accordingly. At the receiver end there are four motors interfaced with the micro controller. Two for the vehicle movement and the remaining two are for arm and gripper movement. Blue control application is used for the controlling of robot. Keywords: Pick and place robotic arm, Blue control app, soft catching gripper
